Not sure if serious... I was looking at that Photoshop presentation, and kept thinking: people who use Photoshop regularly are already familiar with all kinds of keyboard shortcuts, so this isn't new, and has a good chance of not being used. And what about apps which are used for typing? Are you really gonna constantly lift your hands off the main key position every time you need to press some shortcut on the touchbar? A mouse is much easier to use, and is more precise than scrolling across a tiny touch screen. Try scrolling through a video on an iPad vs a computer with a mouse, and you'll quickly realize that a mouse can get to the exact second you need it to 10/10 times, while you're lucky to get there with an iPad 1/10 times.
Apple needs to stop dicking around, and implement touch screens into their computers, and combine that with the pencil for a touch sensitive combination. That would make these systems truly "pro".
